One PPT merger for every job
Merge two PPT files or combine three decks into one. Our PowerPoint combiner keeps your formatting intact either way.
Merge two PPT files into one
Upload two PowerPoint files and download a single combined PPTX. The first file's slides come first, then the second file's.
Combine three decks at once
Our PPT combiner merges up to three presentations in one pass, so you can compile a title deck, the main content, and an appendix into one file.
A PPT joiner that keeps order
Slides stay in the order you upload your files, so your merged deck reads start to finish with no reshuffling.
Merge PPTX files without quality loss
Images, fonts, layouts, and animations carry over untouched. Merging PPTX files never compresses or re-renders your slides.
Editable PPTX, not a PDF
You get back a PowerPoint file you can keep editing in PowerPoint, Keynote, or Google Slides.
Merge any templates together
Decks built from different themes merge cleanly, and every slide keeps its original layout, fonts, and design.
